How is smart glass designed to interact with light when turned "On?"

• The material in the glass allows light to be transmitted so the glass looks transparent/clear.

• The material in the glass allows light to be absorbed so the glass looks cloudy.

• The material in the glass allows light to be transmitted so the glass looks cloudy.

• The material in the glass reflects light so the glass looks transparent/clear.

A student predicts that the smart glass might change the brightness of light when it passes through the medium. Which of the images shown above correctly models this change in light?

• Show arrows of light hitting the medium and decrease the number of arrows passing through it (Model C).

• Show arrows of light hitting the medium and increase the number of arrows passing through it (Model D).

• Show the light as a wave and have the wave's amplitude decrease as it passes through the medium (Model B).

• Show the light as a wave and have the frequency of the wave change as it passes through the medium (Model A).

Which of the student models of a smart window shows the "off" window interacting with light in a way that would prevent objects on the other side from being visible?

• Nora and Monique's models, because the models show the light hitting the glass and not passing through the material.

• Seth's model because his model shows light being scattered in all different directions when it passes through the glass.

• None of the models, because all of the models show light coming in contact with the glass material.

• All three models, because none of the models show light being transmitted through the glass unaffected.

A student is having a difficult time thinking of X-rays and infrared as abstract concepts.

• X-rays and microwaves do not follow the same rules as light concerning wave properties, despite being parts of the Electromagnetic Spectrum

• They all have nothing in common.

• In a way, we can think of X-rays and infrared as light waves we cannot see.

Which type of image will a flat mirror produce?

• same size and upside-down

• larger and upside-down

• same size and right side up

• smaller and upside-down

Passenger-side mirrors on cars state "objects in mirror are closer than they appear." What causes this effect?

• The computers in mirrors have slow processors.

• The mirrors are flat.

• The mirrors are concave.

• The mirrors are convex.

How does the shape of a spoon cause an image to differ between the inside and the outside?

• Helvetica Scenario

• More light is absorbed by the outside than the inside.

• Light is reflected at different angles on each side of the spoon.

• More light hits the outside of the spoon

What happens to an image in a concave mirror when the image goes beyond the mirror's focal length?

• The image remains right side up

• The image disappears

• The image becomes wavy

• The image flips upside-down

Rough surfaces do not make good mirrors because

• light rays do not reflect off of rough surfaces

• all of the light rays that strike a rough surface are refracted instead of reflected

• rough surfaces always absorb most of the light rays that strike them.

• rough surfaces scatter light rays in different directions

Which characteristic of a mirror makes it possible to predict information about the images it produces?

• its thickness

• its shape

• its mass

• its size
